IRRIGATING VALVE.

Application filed January 24, 1921.

To all who/mJ 'it Imay concern.'

Be it known that we, HENRY J. BRUBAKER and JOHN B. BRUBAKER, citizens of the United States, residing at San Dimas, in the county of Los Angeles and State of California, have invented a new and useful Irrigating Valve, of which the following is a specification.

This invention relates to improvements in valve structure and is particularly directed to the construction of a valve adapted for use in irrigating pipe lines or other lines conveying fluids under relatively low pressures. 4

The object of the invention is to provide a valve as a complete device having a concrete or cement body reinforced by a skeleton metal frame which includes the valve seat.

Another object is to provide a valve body comprising a skeleton frame embedded in concrete, providing a valve chamber having an inlet and an outlet opening, the frame providing a valve seat within the chamber and terminating with a top plate adapted to support the valve operating mechanism.

A further object is to provide a. gate valve having a body formed of a skeleton frame embedded in concrete, said frame providing a valve seat and guides for the gate positioned within the v alve chamber. j

'Various other objects andadvantages will be more fully apparent from the following description ofthe accompanying drawings which form a part of this disclosure, and which illustrate a preferred form of embodilnent of the invention:

Of the drawings:

Figure 1 is a longitudinal vertical section through the valve.

Fig. 2 is a plan section on line :r2- m2 of Fig. 1.

Fig. 3 is a plan seot-ionlon line ac3-m3 of Fig, l. j j

Fig. l is a. plan section on line wia-U4 of Fig. 1. j

F ig. 5 is a transverse vertical section through the valve, and K Fig. 6 is a perspective view of the skeleton frame.

Referringy particularly to Fig. 6, the skeleton frame has a top plate or face plate 1 having a central opening ldefining lthe size of the valve chamber and provided with a plurality, of threaded bolt holes 2 adapted to receive the securing bolts 3 by which a Serial No. 439,532.

bonnet or cover plate t is secu-red to the plate l as a closure for the top of the valve chamber. Opposed columns 5 5 extend downwardly from the top plate 1 with their lower ends joined by a circular web "6 having a raised valve seat 7. Each of the columns y5--5 extend inwardly beyond the valve seat 7 and their surfaces adjacent said seat are provided with guide means or guides for the valve discs or gate; these guides may be in the forni of vertically disposed grooves 8-8. Opposed columns 9 9 project downwardly from the top plate 1 on the opposite sides of the central opening therein, with their lower ends joined'y in U-shaped formation and connected with the lower portion of the circular web 6 by a bridge member or post 10. Horizontally valignedwith the axis of the valve seat 7 are opposed bridge members or posts 11-11 connecting each column with the adjacent column 9 and projecting inwardly from each bridge member 11 is an ear or wedge abutment 12 vproviding a cam surface 13' facing the valve seat and angularly disposed relative to the vertical.

In the formation of thervalve body the skeleton frame is positionedyin a suitable form or mould and concrete or cement packed in the form and around theskeleton vframe to form an integral unit providing a valve chamber 14 having end walls 1li-15, the bottom wall 16 and the side walls 17-leach side wall having hub portions 19 of an internal diameter equal tov the internal.

vdiameter of the valve seat Y and formed for connection to concrete, tile or other pipe sections of a pipe line. In they completed lbody the columns 9 are embedded 'at the juncture of the side wall 17 with the end walls 15 with their joined portions following the circular contour of the lower body portion. The columns 5 are partially embedded at the juncture of the side wall 1&5 with the cud walls 15 with the inner surface of the walll 1S flush with the inner surface of the circular web G of the frame. `rl`he end walls 15 are of a thickness sufficient to embed the bridge members 11 therein leaving the grooved portion of the columns 9 exposed and projecting into the valve chamber. Likewise the ears 12;` project beyond lthe inner surfaces of the'end walls for cooperation with the valve mechanism. The contour of the body corresponds withthe contour of the top plate l and the contour of the valve chamber with the contour o't the central openingr in said plate.

This structure provides a valve bod)7 oil cement or concrete reinforced by a skeleton frame Which provides a valve seat within the valve chamber for cooperation with the valve member.

The valve mechanism shown is lof the sliding gate type and comprises a movable valve member or ygate 20 Which in its lower position engages the valve seat to close tlhe passage through vthe valve. The valve member has laterally l.projecting ears 21 extending outwardly from each side edge and sl-idably Iengaging Within the respective grooves 8;'-8

of the columns of the frame to guide the valve in its vertical movements. Wedge blocks 22"-22 rproj ect inwardly from the inner surta-ce of the valve member 2O and are diametricallly 4disposed on opposite sides -ot said member. These `blocks have inclined kcam surfaces 23 adapted to engage the cam surfaces 13 `of the respective frame ears 12 When the valve is in Yclosed position to ivedge the valve to close engagement with the valve sea-t. rThe valve member has latera strengthening ribs and spaced vertical ribs 26 terminating with -a head 27 at the upper niedial .portion of the valve member. Said head has a. circular recess in which is positioned a sW'ivel nut 28 which is bored and threaded to receive a valve operating lrotary stem 129, the lower Wall bet`\veen the ribs 26 and the upper Wall -of the head being cut away to permit the enga-gement olf the stem through the nut. Disengagement ot the nut "28 from its receiving recess is prevented by 'diametrical-ly opposed. ears 30 formed on the nut and engaging Within companion grooves formed in the inner Walls 'of said recess. The length of the ears 30 permit a removal of the nut, when the valve stem 29 is first removed by turn-ing said nut to fbring the ears out of engagement with ltheir grooves aff-ter which said nut may be lifted from the recess.

The valve stem 29 extends through a bore in the bonnet 4 and has a peripheral groove 31 Which Vis engaged by a split ring 32. Said ring is seated yin a recess in the cover plate and retained against displacement by a flanged packing box member 33 having a companion recess engaging over the ring. rJhe member is secured to the cover plate fl by bolts 34, engaging vthrough 'the flanges of `said plate 4 and said member and by nuts 35-engagingftl1e b'olts. A flanged packing gland 36 engages into the member 38 to engage suitable pac-king material 37 to pre'- vent leakage past the valve stem, the pressure of the gland upon said packingmaterial being regulated by nuts y38 engaging the top portions-of the bolts 34:I which project through the harige otfthe gland.

It will be evident from the above that thc ring 32 -niaintains the valve stem 29 against axial translation and that a rotation ot said stem .vill vertically translate the valve member 2O to open or close the valve, the valve sliding in the 'vertical grooves 8 oit the skeleton frame and the wedge blocks 22 engaging the ears 12 of said trame as the valve -is closed to forcibly cam the valve member against its seat 7 when the valve is moved to closed position.

lt will be understood thatv/'hile ive have shoivn and described a gate valve lmechanism olf a `specilic construction, various other valve mechanisms may be employed without departing from the broad scope of the invention yWhich in its major 'aspect is directed to a reinforced valve body in Which the reinforcing element provides a valve seat, and

also 'provides such stationary guides 'and a'butments as the valve mechanism requires.
